TS951IDT - 3 MHz Rail-to-Rail Op Amp | STMicroelectronics
MPN: TS951IDT ✓ פעילTS951IDT סקירה
An operational amplifier, commonly called an op amp, is an active semiconductor component that amplifies the voltage difference between its two inputs. A rail-to-rail input stage accepts common-mode voltages close to either supply rail, while a rail-to-rail output stage can approach the output limits more closely than a conventional amplifier. The TS951IDT belongs to the general-purpose operational-amplifier hierarchy and is suitable for low-voltage analog systems that require useful signal range, moderate bandwidth, and low standby current.
Key characteristics include a 3 MHz gain-bandwidth product, 1 V/us slew rate, approximately 750 uA quiescent current, and a 2.7 V to 12 V supply range. These attributes suit low-power sensor conditioning, buffered instrumentation, audio signal paths, and general analog signal processing. Rail-to-rail input and output operation is particularly useful when signals approach the supply limits or when the amplifier must drive loads with limited voltage headroom.
The TS951IDT uses a BiCMOS operational-amplifier architecture optimized for 3 V and 5 V operation. Its moderate 3 MHz bandwidth provides adequate response for general-purpose signal conditioning without the power and cost of a high-speed amplifier. The 1 V/us slew rate supports noncritical pulse and waveform applications, while the low quiescent current helps conserve energy in portable and battery-powered equipment. Exact offset, noise, output-current, and temperature data must be confirmed in the manufacturer datasheet.
Typical uses include sensor-signal conditioning, analog instrumentation, voltage buffering, audio preamplification, and low-voltage control systems. The TS951IDT can also serve as the active element in passive or active filter designs when component tolerances and loop-gain requirements permit. In portable equipment, its low quiescent current is advantageous, although input bias current and overall system demand should be evaluated before battery-life calculations.
For PCB design, place input, output, and decoupling components close to the SOIC pins. Keep sensitive input traces away from switching nodes and high-current return paths, and use a ground plane that provides a low-impedance return for the amplifier. Bypass the supply pins locally with suitable ceramic capacitance and account for amplifier output loading, stability, and input common-mode limits during schematic review.
This product page combines the TS951IDT electrical identity, package information, sourcing guidance, application analysis, design guidance, and verified replacement search results. It is intended to help engineers identify whether the TS951IDT matches the required bandwidth, supply voltage, package, and low-power characteristics before committing it to a design.

יישומים טיפוסיים
TS951IDT מתאים עבור 6 יישוםs: Low-Power Sensor Signal Conditioning, Portable Instrumentation, Analog Voltage Buffering, General-Purpose Audio Signal Path, Industrial Control and Interface Circuits, Low-Voltage Active Filter.
Low-Power Sensor Signal Conditioning
The TS951IDT fits first-stage conditioning for low-voltage sensor signals because its rail-to-rail input stage accepts common-mode voltages close to the supply rails while drawing approximately 750 uA quiescent current. It can amplify or buffer the sensor output before an ADC or controller. With a 3 MHz gain-bandwidth product and 1 V/us slew rate, the amplifier also provides useful bandwidth for ordinary industrial signals. Place the input path close to the sensor interface and verify offset, noise, and common-mode behavior against the manufacturer datasheet before fixing the gain.
מומלץ
Portable Instrumentation
The TS951IDT suits portable instrumentation designed around 3 V or 5 V supplies because the BiCMOS amplifier is optimized for those voltage rails and operates from 2.7 V to 12 V. Its approximately 750 uA quiescent current helps limit standing power, while rail-to-rail input and output behavior makes more of the available signal range usable. The 8-SOIC package supports conventional surface-mount assembly. Confirm the complete operating-temperature range and offset specifications when designing a battery-powered meter, field probe, or handheld diagnostic device.
מומלץ
Analog Voltage Buffering
The TS951IDT can buffer a high-impedance analog source so that subsequent circuitry does not burden the source with excessive loading. Rail-to-rail input and output operation supports signals near the supply rails, and the 3 MHz gain-bandwidth product is appropriate for moderate-frequency buffer applications. The approximately 750 uA quiescent current is advantageous in compact systems. When using it as a unity-gain buffer, review the manufacturer datasheet for stability, output loading, input capacitance, and output-swing conditions.
מומלץ
General-Purpose Audio Signal Path
The TS951IDT is suitable for modest audio and control-signal amplification stages where a 3 MHz gain-bandwidth product and 1 V/us slew rate are adequate. Rail-to-rail input and output operation can improve signal utilization on low-voltage rails, making the amplifier relevant to compact audio preamplifier or headphone-driver input stages. The approximately 750 uA quiescent current also supports power-conscious designs. Confirm output-current capability, distortion, noise, and load stability in the manufacturer datasheet before driving a specific transducer or loudspeaker.
מומלץ
Industrial Control and Interface Circuits
The TS951IDT can amplify control, feedback, or sensor signals in industrial interface circuits operating from 2.7 V to 12 V. Its 1 V/us slew rate supports general-purpose dynamic signals, while the 8-SOIC package offers a widely used surface-mount footprint. Rail-to-rail operation helps when the interface must process a substantial portion of the supply range. Keep sensitive inputs away from switching power stages and verify the complete temperature range, input-offset limits, and output capability before production release.
מומלץ
Low-Voltage Active Filter
The TS951IDT can implement a general-purpose active filter in a 3 V or 5 V system when the required signal bandwidth remains below its 3 MHz gain-bandwidth product. Rail-to-rail input and output behavior increases the usable signal range, while approximately 750 uA quiescent current limits baseline consumption. Component tolerances and the amplifier's gain-bandwidth behavior directly affect filter response, so simulate the complete network and check stability with the intended source and load. The 8-SOIC package supports compact, surface-mount filter layouts.

הערות תכנון
Place the supply bypass capacitor adjacent to the TS951IDT supply and ground pins, and keep the input and output routing short. Sensitive input traces should remain away from switching nodes and high-current paths because capacitive coupling can appear as input disturbance. Use a continuous ground plane where practical and return output-current and load currents directly to the supply system rather than through signal-ground paths.
Design around the 2.7 V to 12 V supply range and the approximately 750 uA quiescent current. The device is optimized for 3 V and 5 V operation, so those rails generally provide the intended operating characteristics. Check output swing, load current, supply ripple, and power dissipation under worst-case conditions. Do not infer full rail-to-rail output capability or unlimited output current without consulting the manufacturer limits.
Rail-to-rail input and output operation does not remove the need to verify input common-mode limits, output swing, stability, and load capability. When replacing TS951IDT, compare the complete pin function rather than relying only on the 8-SOIC outline. Also confirm that the alternative supports the intended 3 V or 5 V supply, provides adequate bandwidth, and meets the noise and offset requirements of the signal chain.
